My SES light came on tonight for the first time since i've had my car. I have I/E and haven't added any mods to my car for at least a couple months... the car sounds the same and seems to drive the same, how do I figure out why the SES light is on and what needs to be fixed? Thanks for any and all help!

Thanks! So basically it looks like it has something to do with one of my o2 sensors... I wonder why it said something about the crank shaft position at the top though... i had a recall done about that a while back. Anyone have any ideas, suggestions, or experiences with this and how to fix it? Thanks for all the help!

perhaps there can be a malfunction of the cam shaft position sensor that could cause the O2 sensor to also malfunction. Not sure. It could be the sensor again though man...I have had mine replaced 3 times.

Dang, thanks for the info I made an appointment to take her into the nissan dealership on wednesday and since im still under warranty they said they would check it out for no charge. I'm hoping its a free fix too.

Well the car is at nissan right now... been there most of the day... the service guy told me that since it is under warranty that they will just find the problem and fix it for me. no trouble at all.
